Abstract
A circuit breaker system (,) providing a low impedance magnetic latch tripping scheme. The circuit breaker system (,) includes a trip unit (,) coupled to a switch unit (,). Trip unit (,) is coupled to an electrical circuitry and utilizes a current transformer (,) to sample a current conducting through the electrical circuitry. This current is processed into an input signal (,) suitable as an input to a trip circuitry (,) included in the trip unit (,). When a processor (,) senses an overcurrent condition in the input signal (,), processor (,) transmits a trip signal (,) to a switch (,) to initiate protection against the overcurrent condition, i.e., a trip of the electrical circuitry. Switch (,) permits a low release current to conduct through a low impedance electromechanical interface unit (,) such that the electromechanical interface unit (,) can actuate a mechanical opening mechanism included in the switch unit (,).
